Master File TableDepending on the average file size and other variables, either the reserved MFT zone or the unreserved space on the disk may be allocated first as the disk fills to capacity. Volumes with a small number of relatively large files will allocate the unreserved space first, while volumes with a large number of relatively small files allocate the MFT zone first. In either case, fragmentation of the MFT starts to take place when one region or the other becomes fully allocated. If the unreserved space is completely allocated, space for user files and directories will be allocated from the MFT zone. If the MFT zone is completely allocated, space for new MFT entries will be allocated from the unreserved space.

As the core of NTFS, the MFT plays an important role in the composition of an NTFS volume and its performance. The MFT continually references files as the system locates data, reads from the data, and writes the data to the disk. Thus, the performance of the MFT is essential to the performance of the entire volume.
NTFS's developers understood the importance of the MFT's performance and took steps to ensure that the MFT maintains high performance during its lifetime. First, NT automatically places the MFT at the beginning of the disk when you first format an NTFS volume. The outer tracks of a disk yield the highest rotational and data transfer rates, and most NTFS volumes correspond to an entire physical disk; thus, the MFT's placement at the beginning of the disk minimizes the time that MFT-related disk I/O operations require. Second, NTFS's developers addressed potential MFT fragmentation by creating a special buffer zone around the MFT, which the NTFS volume reserves for use by the MFT. By default, this buffer zone uses approximately 12.5 percent of the disk. Although this allocation usually minimizes MFT fragmentation, sometimes the buffer zone isn't adequate.
